Stick on drywall corner cover

ABSTRACT

A stick-on drywall-corner cover for covering predetermined drywall-corner configurations has a stick-on first cover-attachment panel ( 2 ) and a stick-on second cover-attachment panel ( 3 ) with undetectably thin panel edges ( 7 ) on opposite sides of a corner portion ( 4 ) that is predeterminedly rigid. The thin panel edges can be paper layers ( 19 ) or thinly tapered edges ( 18 ) of rigid material ( 21 ) for stick-on covering of foreseeable drywall-corner configurations.

BACKGROUND OF THE INVENTION

This invention relates to covers of drywall corners preparatory to wall surfacing for building construction.

Numerous items, devices and methods for covering drywall corners for building construction are known. None, however, are known to have a desirably surfacable drywall-corner cover that can be articulated to fit onto and to be adhered to numerous configurations of drywall corners and to form undistinguishable cover-edge ridges in a manner taught by this invention.
